| Abstract: |
| A method of automatic generation of three-dimensional mesh in order to raiseprecision and efficiency in solving flow problem with finite element method is discussed in this paper.With algebraic mapping technique only a few of boundary data is needed to gone rate the interio-grid.Two examples for generating automatic three-dimensional mesh are also presented. |
